Morphology

stegosaur = stego + saur

Formed from Greek combining forms ('stego-' + '-saur') that are not standalone English words, so an average learner cannot derive the meaning from familiar English base words.

Etymology

The word stegosaur comes from two Greek parts: stego- meaning 'roof' and -saur meaning 'lizard', the same -saur you see in dinosaur. Its bony plates stand up along the back like a 'roof', so the name is like calling it a 'roof-lizard' and helps explain its plated look.
